Examination of One Month Retention of Executive Function in Assisted Cycling Therapy on Adolescents with Down Syndrome

Description
This study examines the one month retention of executive function benefits gained by adolescents with Down syndrome after an 8-week aerobic exercise intervention. Sixteen participants were randomly divided between voluntary (VC) (i.e., self-selected cadence) and assisted (AC) (i.e., 30% faster than self-selected cadence accomplished by a motor) cycling groups, with…

This study examines the one month retention of executive function benefits gained by adolescents with Down syndrome after an 8-week aerobic exercise intervention. Sixteen participants were randomly divided between voluntary (VC) (i.e., self-selected cadence) and assisted (AC) (i.e., 30% faster than self-selected cadence accomplished by a motor) cycling groups, with one participant used as a control (NC). Both cycling groups rode a stationary bicycle, for 30 minutes, three times a week, for eight weeks. At the beginning (i.e., pretest) and end (posttest) of the 8-week session, three executive functions including: set-switching, inhibition, and cognitive planning, were tested. Approximately one month after the posttest, all participants underwent the cognitive testing again. The results showed that for the AC group cognitive planning improved after eight weeks of assisted cycling and these improvements were maintained after one month of no cycling. However, no significant differences were found between the cycling groups for our measure of inhibition. Set-switching appeared to be improved by both types of exercise, rather than only assisted, but the improvements were not maintained during the one month retention period for either group. Thus, our results suggest that Assisted Cycling causes potentially permanent changes in the brain in regards to cognitive planning.

Is daily activity and exercise related to physical fitness, obesity, and mental health in adolescents with Down syndrome?

Description
The aim of this study is to understand the relationship among physical fitness, leisure-time activity levels, measures of body composition, and assessments of emotion toward physical activity in individuals with Down syndrome (DS). This is important because it could help individuals understand the importance of physical activity in this population.…

The aim of this study is to understand the relationship among physical fitness, leisure-time activity levels, measures of body composition, and assessments of emotion toward physical activity in individuals with Down syndrome (DS). This is important because it could help individuals understand the importance of physical activity in this population. The BMI, waist circumference, height, weight, body fat percentage, and non-exercise estimation of aerobic capacity along with the temporary state of emotion toward physical activity of thirty participants with DS were measured. The results of our study show that individuals with DS who are more physically fit have less body fat and a lower BMI. They also took part in more leisure-time activity and expressed more effort during physical activity.
